I didn't know it until reading the latest Classic Trains magazine, but the SP owned only one RDC, No. 10. Pretty cool. Reading further elsewhere, I find that it survives and is on its way to a museum for restoration. Check out those numberboards!
That would be a great addition. I could keep the branchline operators honest by running this along the main and back.
I didn't want to start a new thread, but I found an interesting picture in Beebe & Clegg's The Trains We Rode Vol. II of an of an SP passenger train at the Santa Fe's San Diego station behind a 4-6-0. Interestingly, the SP operated a San Diego connection with the SP/Rock Island Golden State that ran to Yuma, AZ via the SD&AE. The photo shows a four car heavyweight train with a Pullman. I never realized that San Diego's station was once a Union Station.
Built by Budd in 1954 as SP #10 and used on the money-losing local service routes between Sacramento and the Oakland Pier, replacing more expensive-to-operate locomotive-hauled trains. It was then leased to Northwestern Pacific where a grade crossing collision in 1960 resulted in one cab end being rebuilt to a baggage section. Sold to Yreka Western in 1971 and became #100. It ended up at the Galveston Railroad Museum where it was sometimes used as power to move other equipment around. After it broke down and needed major repairs, it was sort of neglected. During Hurricane Ike it was badly flooded with sea water. They finally sold it to the California group who had the funding and interest to restore it. In January 1998, a buddy of mine, Santa Fe Historian Steve Sandifer, obtained permission to climb up on top of the collection at Galveston to document the roof details on some of the Santa Fe equipment one morning before the museum opened. He dragged me along to help out toting much of his gear. I was having just as much fun checking out all the other stuff.
